[0039] Figure 11 is a schematic diagram of an electronic device 100, a router 102, and a network server 104 according to an embodiment of the present invention. In some embodiments, the electronic device 100 may be a user equipment (UE), such as a smart phone, a tablet, a laptop computer, or a machine type communication (MTC) device, but the present invention is not limited thereto. In some embodiments, the router 102 may be a Wi-Fi hotspot, an evolved Node B (eNB), or a next generation Node B (gNB), but the present invention is not limited thereto. In some embodiments, the network server 104 may include a wireless LAN (WLAN), or an evolved universal terrestrial radio access network (E-UTRAN) and an evolved packet core (EPC), or a next generation radio access network (NG-RAN) and a next generation core network (NG-CN), but the present invention is not limited thereto.

[0040] like Figure 1 As shown, the electronic device 100 includes a TX delay monitor 110, a wireless monitor 112, and a wireless network environment checker 114. In some embodiments, the TX delay monitor 110, the wireless monitor 112, and the wireless network environment checker 114 may be arranged in one or more processors, but the present invention is not limited thereto. In some embodiments, the TX delay monitor 110, the wireless monitor 112, and the wireless network environment checker 114 may be one or more processors, but the present invention is not limited thereto.

[0041] In some embodiments, the TX delay monitor 110 is included in the wireless network device, but the present invention is not limited thereto. The user space may be an application executed on the electronic device 100, but the present invention is not limited thereto. The TX delay monitor 110 sends a TX delay event to the wireless monitor 112 in response to the TX delay associated with the TX data packet being longer than a predetermined period of time. The wireless monitor 112 sends a warning signal to the wireless network environment checker 114 through the data path 160 based on the TX delay event.

[0042] In some embodiments, the wireless monitor 112 executes the core algorithm 170 to monitor TX delay events through the data paths 120 and 122 (block 172), sets parameters of the TX delay monitor 110 through the data paths 124 and 126 (block 174), receives TX delay events from the TX delay monitor through the data paths 130 and 128 (block 176), and sends a warning signal to the wireless network environment checker 114 based on the TX delay events. In some embodiments, the parameters of the TX delay monitor 110 set by the core algorithm 170 include a predetermined period. The predetermined period is a threshold period set by the core algorithm 170.

[0043] In some embodiments, the TX delay monitor 110 calculates the TX delay associated with the TX data packet. In some embodiments, the TX delay monitor 110 executes the TX delay monitoring driver 178 to calculate the TX delay associated with the TX data packet, and in response to the TX delay associated with the TX data packet being longer than a predetermined period, sends a TX delay event to the wireless monitor 112. In some embodiments, the TX data packet is received by a network interface (not shown) in the electronic device 100, but the present invention is not limited thereto. In some embodiments, the TX data packet is sent from a user space, but the present invention is not limited thereto.

[0044] For example, the TX delay monitor 110 executes the TX delay monitoring driver 178 to record a first time point at which a TX data packet is sent to a hardware queue in the wireless network device. The hardware queue stores the TX data packet to be sent to the router 102. The TX delay monitor 110 executes the TX delay monitoring driver 178 to record a second time point at which the TX delay monitor 110 receives an acknowledgment message from the router 102. The second time point is later than the first time point. Thereafter, the TX delay monitor 110 calculates the TX delay associated with the TX data packet by subtracting the first time point from the second time point. In response to the TX delay associated with the TX data packet being longer than a predetermined period of time, the TX delay monitor 110 executes the TX delay monitoring driver 178 to send a TX delay event to the wireless monitor 112.

[0045] In some embodiments, in response to receiving the warning signal from the wireless monitor 112, the wireless network environment checker 114 checks one or more of the wireless signal received signal strength indication (RSSI) (box 180), network delay (box 182), network bandwidth (box 184), and other wireless related indicators (box 186). In some embodiments, the other wireless related indicators may include idle time, but the present invention is not limited thereto. The wireless related indicators detected by the wireless network environment checker 114 depend on the optimization purpose or specific requirements.

[0046] In some embodiments, when the electronic device 100 is turned on, the wireless monitor 112 is initialized. During the initialization, the core algorithm 170 sets the parameters of the TX delay monitor 110 through the TX delay monitoring driver 178 (e.g., box 174). For example, the threshold period is set to 5 milliseconds and the threshold interval is set to 200 milliseconds. Thereafter, the wireless monitor 112 starts to monitor the TX delay event. When the wireless network environment becomes worse, the TX delay monitor 110 executes the TX delay monitoring driver 178 to calculate the TX delay of 10 milliseconds. Therefore, in response to the TX delay (e.g., 10 milliseconds) associated with the TX data packet being longer than a predetermined period (e.g., 5 milliseconds), the TX delay monitor 110 executes the TX delay monitoring driver 178 to send a TX delay event to the wireless monitor 112.

[0047] Then, the wireless monitor 110 executes the core algorithm 170 to receive the TX delay event from the TX delay monitor 112. In some embodiments, the wireless monitor 112 records the TX delay event (e.g., 10 milliseconds of TX delay) but does not send a warning signal to the wireless network environment check 114. In some embodiments, when the wireless monitor 112 receives 5 consecutive TX delay events less than 20 milliseconds during 500 milliseconds, or obtains a TX delay event greater than 20 milliseconds, the wireless monitor 112 sends a warning signal to the wireless network environment checker 114 through the data path 160. Thereafter, in response to receiving the warning signal from the wireless monitor 112, the wireless network environment checker 114 checks one or more of the wireless signal received signal strength indication (RSSI), network delay, and network bandwidth.

[0048] Get the wireless network environment checker 114 Figure 1 After receiving the results of blocks 180 to 186 in the wireless network environment checker 114, the wireless network environment checker 114 performs a network quality evaluation calculation to provide an evaluation result of the real-time wireless environment. In some embodiments, if the evaluation result is not good, the wireless network environment checker 114 sends the evaluation result to the user space. In some embodiments, the wireless network environment checker 114 performs a network quality evaluation calculation based on a benchmark obtained from a specification through the network. After the user space receives the evaluation result of the wireless network environment checker 114, the user space can perform optimization and adjustment by adjusting the resolution to reduce bandwidth usage, or switch to other networks and other strategies.

[0049] In some embodiments, when the wireless monitor 112 finds that there is no TX data packet during 100 milliseconds, the wireless monitor 112 can actively send a ping packet to the router 102 to avoid a long period of no monitoring events.

[0050] Figure 2 According to an embodiment of the present invention, Figure 1 Schematic diagram of the definition of TX delay calculated by the TX delay monitor 110 in FIG. Figure 1 and Figure 2 .like Figure 2 As shown, at time point T0, the user space sends data to the electronic device 100 (block 200). In some embodiments, the user space may be an application executed on the electronic device 100, but the present invention is not limited thereto.

[0051] Specifically, the TX delay monitor 110 is included in a wireless network device having a hardware queue for preparing to send a TX packet to the router 102. The TX delay monitoring driver 178 is included in the wireless network interface driver. Therefore, after receiving the TX packet from the wireless monitor 112, at time point T1, the wireless network interface driver sends the TX packet to the hardware queue in the wireless network device (block 202). In some embodiments, the period from time point T0 to time point T1 is considered as the driver delay.

[0052] At time point T2, the TX delay monitor 110 (or wireless network device) sends the TX data packet stored in the hardware queue into the air (block 204), such as via an antenna, and such as via Figure 1 In some embodiments, the time from time point T1 to time point T2 is regarded as the hardware queue buffering time.

[0053] When the router 102 receives the TX data packet from the electronic device 100, the router 102 sends a confirmation message back to the electronic device 100 and sends a confirmation message to the electronic device 100, for example, by Figure 1 1 and 10. The TX packet is forwarded to the network server 104 along the path 150 in the example. In some embodiments, the confirmation message from the router 102 is a layer 2 (L2) confirmation (ACK) message, but the present invention is not limited thereto. At time point T3, the TX delay monitor 110 receives the confirmation message from the router 102 (block 206). In some embodiments, the TX delay of the present invention is defined as a period from time point T1 to time point T3, but the present invention is not limited thereto.

[0054] After the network server 104 receives the TX data packet forwarded by the router 102, the network server 104 sends an Internet Protocol (IP) data packet to the electronic device 100. The router 102 then forwards the IP data packet, and the TX delay monitor 110 receives the IP data packet from the network server 104 at time point T4 (block 208). Since the TX delay of the present invention is defined as the time period from time point T1 to time point T3, the TX delay can fully respond to the interference or scenario of the wireless environment where the user is located.

[0055] Figure 3 According to an embodiment of the present invention, the Figure 1 Flow chart of the low-power wireless network environment monitoring method of the electronic device 100. Figure 3 As shown, the method of the present invention includes the following stages. The TX delay monitor 110 calculates the TX delay associated with the TX data packet (step S300). The TX delay monitor 110 sends a TX delay event in response to the TX delay associated with the TX data packet being longer than a predetermined period of time (step S302). The wireless monitor 112 receives the TX delay event and sends a warning signal to the wireless network environment checker 114 according to the TX delay event (step S304). The wireless network environment checker 114 checks the network communication environment in response to receiving the warning signal from the wireless monitor 112 (step S306).

[0056] In some embodiments, before executing step S300, the wireless monitor 112 sets parameters of the TX delay monitor 110. For example, these parameters include the predetermined time period in step S302, but the present invention is not limited thereto. In step S300, the TX delay monitor 110 records the first time point when the TX packet is sent to the hardware queue (e.g., Figure 2 The TX delay monitor 110 records the second time point (eg, time point T1) at which the TX delay monitor 110 receives the confirmation message from the router 102. Figure 2 The TX delay monitor 110 calculates the TX delay associated with the TX packet by subtracting the first time point from the second time point. That is, the TX delay is equal to Figure 2 In some embodiments, the TX delay monitor 110 is configured to monitor the time period from the time point T1 to the time point T3 at the third time point (eg, Figure 2 At time point T4 in the figure, an IP data packet is received from the network server 114.

[0057] In step S302, the wireless monitor 112 receives the TX delay event from the TX delay monitor 110, and then executes step S304. In step S304, the wireless monitor 112 may directly send a warning signal to the wireless network environment checker 114 based on the TX delay event. In some embodiments, the wireless monitor 112 may record the TX delay event but does not send a warning signal to the wireless network environment checker 114. In the initialization phase after the electronic device 100 is turned on, a policy for the wireless monitor 112 to send a warning signal is set.

[0058] In step S306 , the wireless network environment checker 114 checks one or more of the wireless signal RSSI, network delay, and network bandwidth in response to receiving the warning signal from the wireless monitor 112 , but the present invention is not limited thereto.

[0059] The low-power wireless network environment monitoring method and electronic device 100 of the present invention use TX delay as the detection indicator of the first stage, which requires the support of TX delay monitor 110 and TX delay monitoring driver 178. TX delay monitor 110 records and monitors Figure 2 The period from time point T1 to time point T3 in the first stage is a low-power operation. When the detection index of the first stage is determined, the wireless monitor 112 sends a warning signal, so that the wireless network environment checker 114 performs the actions described in blocks 180 to 186 as the detection index of the second stage, which is an operation with high power consumption. The low-power wireless network environment monitoring method and the electronic device 100 of the present invention can significantly reduce the number of detections in the high-power second stage, thereby achieving the purpose of reducing power consumption.

[0060] Although the present invention has been described in conjunction with certain specific embodiments for illustrative purposes, the invention is not limited thereto. Accordingly, various modifications, adaptations and combinations of the various features of the described embodiments may be practiced without departing from the scope of the present invention as set forth in the claims.
